Z boson decay to photon plus Kaluza - Klein graviton : large extra dimensional bounds

چکیده

We consider the phenomenology of the decay of a Z boson into a photon and a Kaluza-Klein excitation of the graviton in the ADD model. Using LEP data, we obtain an upper bound on the branching ratio corresponding to this process of ∼ 10. This bound would be useful for model discrimination in the event of such a signal at a future collider. We also investigate energy profiles of the process, showing that with sufficient data this process could distinguish between numbers of extra dimensions in the event of discovery of a toroidally-compactified ADD model.

Z boson decay to photon plus Kaluza-Klein graviton in large extra dimensions

In the large extra dimensional ADD scenario, Z bosons undergo a one-loop decay into a photon and Kaluza-Klein towers of gravitons/gravi-scalars. We calculate such a decay width, extending previous arguments about the general form of the fourdimensional on-shell amplitude. The amplitudes calculated are relevant to processes in other extra dimensional models where the Standard Model fields are co...

Production of a Z boson and photon via a Randall-Sundrum-type graviton at the Large Hadron Collider

In extra dimensional models with Kaluza-Klein graviton states that are well separated in mass, such states may be observed as resonances in collider experiments. We extend previous works on such scenarios by considering the one-loop resonant production of a Z boson in association with a photon. We find the production rate to be negligible in conservative scenarios, and small for reasonable lumi...

Direct collider signatures of large extra dimensions

The realization of low (TeV) scale strings usually requires the existence of large (TeV) extra dimensions where gauge bosons live. The direct production of Kaluza–Klein excitations of the photon and Z–boson at present and future colliders is studied in this work. At the LEPII, NLC and Tevatron colliders, these Kaluza–Klein modes lead to deviations from the standard model cross-sections, which p...

Graviton Production By Two Photon Processes In Kaluza-Klein Theories With Large Extra Dimensions

We consider the production of gravitons via two photon fusion in Kaluza-Klein theories which allow TeV scale gravitational interactions. We find that the processes ll → ll + graviton, with l = e, μ can put quite stringent bounds on such theories. For example, with two extra dimensions at the Next Linear Collider with a center of mass energy of 500 (1000) GeV attainable bounds on the scale of th...
